There are clearly no hard feelings between Jana Kramer and her estranged husband Mike Caussin based on the words of appreciation Kramer offered him on Father's Day.

The country singer took to Instagram on Sunday (June 18) to share an adorable photo of Caussin and their 1-year-old daughter, Jolie Rae, on her dad's shoulders. "We may not have the perfect fairytale love story but what is perfect between us is our little girl. Happy Father's day to Jolie's daddy," Kramer writes. "There's one thing we can for sure always agree on... you're an amazing father and she's so lucky to have you."

Caussin is a former NFL tight end, playing for the Buffalo Bills and Washington Redskins. He and Kramer met on Twitter in 2014 and married a year later. They broke it off in 2016 after reports of Caussin's infidelity, but may be working on their marriage. The two reunited at an LA Dodgers game in 2017 where Kramer threw out the first pitch.

Kramer, an actress, made her debut on the country music scene in 2013 with "Why You Wanna" following a tenure on the popular teen drama One Tree Hill in the role of Alex Dupre. She gave birth to daughter Jolie in January of 2016, and she says being a mom has been her best role yet.

“I love acting, I love singing, but I’ve always felt like there was something missing," the singer says in an interview with Yahoo! about her daughter. "I never really knew what my purpose was, and I honestly didn’t figure out that purpose until I had Jolie."
